Checking to see if someone has updated a form

VBGuy2112 · Jun 28, 2002

Hello. I'm looking to write a generic function that will check all elements of a form to see if any field has been updated. What I mean is, I'd like to take a snapshot of all the values on a form when it's loaded and then check it at submission time to see if the user has changed any of the fields. If it's changed, then I want to update a record and create an audit trail.

I'd like to have this be a generic function that will work on any form. Any ideas?

Thanks!

<body onload="GetFormData()">

<form ... onSubmit="CheckFormData()">
...
</form>

<script language=javascript>
var myDataArray = new Array();
function GetFormData() {
for (i=0;i<document.forms[0].elements.length;i++)
{
myDataArray = document.forms[0].elements.value
}
}
function CheckFormData()
{
for (i=0;i<document.forms[0].elements.length;i++)
{
if (document.forms[0].elements.value!=myDataArray) {
alert(document.forms[0].elements.name + " has changed" }
}
}
</script>
